Hi Paul, The conversion of rockchip-rga.txt to rockchip-rga.yaml by myself just has been approved by robh. Maybe place dts patches at the end of a patch serie. Could you include a &rga patch if your device is supported in mainline, so we can test with: make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-rga.yaml Johan On 4/16/20 1:50 PM, Paul Kocialkowski wrote: > The PX30 features a RGA block: add the necessary node to support it. > > Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com> > --- > arch/arm64/boot/dts/rockchip/px30.dtsi | 11 +++++++++++ > 1 file changed, 11 insertions(+) > > diff --git a/arch/arm64/boot/dts/rockchip/px30.dtsi b/arch/arm64/boot/dts/rockchip/px30.dtsi > index 75908c587511..4bfbee9d4123 100644 > --- a/arch/arm64/boot/dts/rockchip/px30.dtsi > +++ b/arch/arm64/boot/dts/rockchip/px30.dtsi > @@ -1104,6 +1104,17 @@ vopl_mmu: iommu@ff470f00 { > status = "disabled"; > }; > > + rga: rga@ff480000 { > + compatible = "rockchip,px30-rga"; > + reg = <0x0 0xff480000 0x0 0x10000>; > + interrupts = <GIC_SPI 76 IRQ_TYPE_LEVEL_HIGH 0>; > + clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA_CORE>; > + clock-names = "aclk", "hclk", "sclk"; > + resets = <&cru SRST_RGA>, <&cru SRST_RGA_A>, <&cru SRST_RGA_H>; > + reset-names = "core", "axi", "ahb"; > + power-domains = <&power PX30_PD_VO>; status = "disabled"; > + }; > + > qos_gmac: qos@ff518000 { > compatible = "syscon"; > reg = <0x0 0xff518000 0x0 0x20>; >

Huh, I looked around for ongoing related work but missed it. I'll definitely rebase on top of your series and use the yaml description instead.

Did that change? Since it's a standalone block that has no I/O dependency, I don't really see the point of disabling it by default. What do you think?

Well, these blocks do have related I/O ports so it makes sense not to enable them by default because of pinmux, or because there might be no connector populated/routed. For a memory to memory internal block, I don't see any reason why. It's definitely not board-specific and having to add these nodes for every board that has them is kind of a pain and might be overlooked. This will easily result in the feature not being available for end users without having to change the dt. Also, the vpu node is always enabled on rockchip (and sunxi) platforms. I think these are better examples to follow.

And removing nodes from dt is certainly not an appropriate way to do power management! Device-tree is a way to represent the hardware, not a configuration interface (well, besides the /chosen node). Besides, the RGA driver seems to have good runtime pm support, so be assured that its clocks will be off when unused.

Yes, as far as I'm aware the general preference for things that are entirely internal to the SoC and don't have any external dependencies like regulators or pinctrl settings is to leave them enabled by default. There's nothing to gain from disabling them, and in fact if the hardware would otherwise just sit there idle in its out-of-reset state then allowing a driver to bind and enable power management may be a distinct benefit. Whether a board wires up video output or not is also largely orthogonal to whether internal graphics/video accelerators are useful. Consider how many people use their NAS box for media transcoding, vs. how many would ever plug a display directly into said box if it even has a connector. If the RGA can be wired into some software format conversion/scaling/whatever pipeline then it's useful full stop. Robin.
